now i wish i remembered all the different tests that were done on these swords in The Deadliest Warrior

i remember that the gladius was a pretty basic weapon, doing 'alright' in cutting but excelling at thrusting (which is what it was designed for when paired with a roman shield).
For that shape of machete, i think all the weight is drawn into the curve (dont quote me on that, it looks like the one from deadliest warrior i saw but i dont know what type of warrior used it to research specifically) for a strong sweep motion. The overall design for sure is meant to slice rather then thrust so great if your agile and like to do a lot of arm work.
For convenience of sheathing, the gladius just goes right in and out of the sheath, but the machete needs the clasps undone to sheath/unsheathe which may prove troublesome if you are to actually carry these with you on site
This is all from what i can remember when i go back to watching deadliest warrior, i dont have any definite experience with these things or what they are able to achieve in combat
